Four New Glass-Mat Products Complete the USG Portfolio

Sheetrock® Brand Glass-Mat Panels MoldTough® AR

USG Corporation (NYSE: USG) announces the completion of its glass-mat portfolio with the addition of four new products.

New exterior product:
• USG Securock® Brand Glass-Mat Sheathing – High-performance sheathing for warranted protection from the elements, with new and improved coated fiberglass facer mat to maximize coverage of air/water barrier systems.

New interior products:
• USG Sheetrock® Brand Glass-Mat Panels Mold Tough® AR – High performance interior fiberglass-faced panels, offering greater resistance to surface indentation and impact damage than standard gypsum panels.
• USG Sheetrock® Brand Glass-Mat Panels Mold Tough® VHI – An upgrade to abuse-resistant panels, these high performance interior panels offer very high impact resistance and added resistance to surface indentation and impact damage.

New wet area product:
• USG Durock™ Brand Glass-Mat Tile Backerboard – For use in wet areas where moisture- and mold-resistance is required, these panels combine cement board-like tile bond with the handling and ease of use of a USG Sheetrock® Brand gypsum panel.

“In an effort to provide the industry’s most robust wallboard portfolio with best-in-class service, USG now offers customers a choice for all of their glass-mat needs,” said Greg Salah, Senior Vice President & General Manager, North American Gypsum at USG. “The full-line of high-performance products includes a new coated sheathing, four interior glass-mat panels, a shaftwall liner panel, a new tile backerboard and a roof cover board, all engineered with moisture and mold resistance.”

Why USG’s Glass-Mat Portfolio

All USG fiberglass-faced products feature an inorganic water-shedding glass-mat enclosure and a fire-resistant gypsum core that is treated to achieve the highest ASTM measured mold-resistance rating available.

The USG glass-mat portfolio, recognized by the distinctive green color, delivers a complete moisture- and mold-resistant solution under three trusted brand names: USG Sheetrock® Brand for interior applications, USG Securock® Brand for exterior applications, and USG Durock® Brand for tilebacker applications.
